As the Scripture says after the Blood of Jesus there was no need for another blood to be shed.
This Blood was shed to remove the sinful nature in mankind. The blood of Adam was found running.
Through the blood of mankind generation after generation and there was no blood so pure that was find that could save mankind from this sinful nature. Even the garment that God made for Adam and Eve did not remove the sin that was in them but just covered.
When the Blood of Jesus that was pure and unblemished fell on the ground, the ground that represented human, for man was made from the soil. So at this point the ground that received the Blood of Jesus was the mankind. When the Blood fell on the ground it did not flow upon the earth but it fell upon the head of man, went down to the mind and purified the mind of man and went down to the heart that pumps the blood and this blood dominated the body and every vein was filled with this pure blood.
That is why man has to be born again. So as to inherit this pure blood from the adoptive Father God.
The blood of Jesus was the only blood that was found pure and the only one that could remove the sinful nature in man when injected with this blood.
JESUS BLOOD IS STILL STRONG EVEN TODAY TO SAVE.
